I have a problem and I dont’t know the cause. I use Magento 2.3.4.
I created an cofigurable product with more sizes and I tryed to disable or remove an “Virtual product” because i don’t need those sizes.
After I disable an product another sizes disappear from dropdawn list in frontend even if they are enable and is in stock.
I attached 2 images to be easier to see where is the problem.
Thank you! And sorry if my english is not so good :D.
